DELIVERY MECHANISM FOR MACHINES FOR OPERATING 0N PAPER.

Specification of Letters Patent. Patnted June 21, 1921,

Original application filed May 11, 1917, Serial No.-167,855. Divided and this application flled llay 4,

1918. Serial No. 232,607.

To all whom it may concem: Beit known that I, HOWARD G. WIDMER, a citizen of the United State s,and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Delivery Mechanism for Machines for-Opcrating on Paper.

This inventionseeks to provide convenient and efiicient mechanisms for handling and delivering paper units as they come from a machine for operating upon paper. The invention is especially designed to work in connection with the machine shown and described in the pending application filed by me on May 11, 1917, Serial No. 167,855, now Patent 1,362,976 granted December 21, 1920, by means of which paper tubes are formed of crinkled paper. Aftersuch tubes have been formed, they are delivered from the machine by means of the mechanism herein shown and described.

The present application is a division of my earlier'application abovereferred to.

In the accompanying drawings forming part of this specification, and in which like reference numerals designate corresponding parts, the invention and its various features are shown in the preferred form.

.In the drawings, Figure 1; is a sectional elevation of the mechanism in operativeassembly.' V Fig. 2. is a' sectional elevation of a detail.

. i Fig. 3 is a plan view of Fig. 2.

Fig. 4 is a rear sectional view taken on the line 4-4 of Fig. 1.

Referring now to the particular structure shown in the :drawings, 1 is the main frame of the machinein which are mounted two-rolls 2 and 3 which cooperate "to complete the formation of aLtube from'a sheet of crinkled. paper, as described in'my patent above. referred to. Such tube is completed by. forming. a scam in the twoadjoining margins ofjthefsheet, such seam'extending lengthwiseof the tube. As the tube passes between rolls 2 and 3 it is held on roll 3 at both its leading and following margins by suitable grippers, the seam being in the following margin having been'formed by the use, of paste. In [order that the freshly pasted seam may notbe. injured, it is desir able. toreverse the lea'dingend. of the tube before delivering, it to the carrier tapes which are to remove itfrom the tube for-me ing machine. 7 For this purpose a pan. is employedto receive each tube as it comes from the rolls 2 and 3 and reverse its leading end.

4 is a tube which has justbeen deposited in the receiving pan 5 from roll 3. Pan 5 has a high back and a sloping bottom and is open on its sides. It is located between the rear horizontal extensions of'the main frame 1 and is arranged to slide to and fro thereon. For this purpose angle brackets Gand- 7. are secured to the bottom of the pan on either side and to U-shaped slide bars 8 and 9 which extend from the front of the pan to a short distance inthe rear thereof. These slide bars are held in place by guide bars 10 and 11 carried bythemain frame. Bolts ed to the slide bars 8 and 9 are drawbars 12 and 13 extending to the rear and provided at their rear ends with rollers 14. These draw bars are provided with slots 15 111111181 diately in front of their rollers 14 through which slots passes a shaft 16 mounted in the main frame. Fix'ed' to. each 1 end of this shaft is a cam l7 and a friction wheel 18f,

By this arrangement, as theshaft 16 rotates, V

the cam s carried by it contactwiththe roll ers'14 pushing thelnto the rear and thereby carrying the pan 5 rearward. When the cams have passed out of contact with the rollers 14, springs 20 pull the pan forward into the position shown in Fig.1. The pan has thus a reciprocating movement, from and toward the roll 3. Whenthe panis close to theroll 3, as shown in Fig. 1, the grippers on roll 3holding. the forwardlend of the tube when theyhave. reached a point just above th forward end ofthe .panre lease the tube so that this end of the tube'is deposited in the receiving pan in which-the forw'ardmarginof the tube comes to rest against the back of the pan. The body of the tube, after forming one or twoeloops, overhangs the front of the panas shown in Fig. 1. In order that therearspprtion of the tube may thus overhang the pan, the lat I ter is caused to move to the rear by mechanism already described. Whenabout. fourfifths of the tube has been deposited in the pan and the rippers on roll 3 holding the rear end of the tube have reached. a point well in front of the pan, they release their suitable guide pulleys and run in the same direction closetogether from a point where the tube is deposited between them'to and around the roll 23 where they separate, the tapes 22 passing entirely around the roll 23 and thence down and back to the starting' point, and the tapes 21' passing over the top of the roll 23 andthence around a roll 24 and to their starting point. The tapes 22 1 are driven by the roll 23 on the shaft 43 on which are also fixed a sprocket wheel 25 on the near end of the shaft and a second sprocket wheel (not shown) on the far endof the shaft. The tapes 21 are driven'by the roll 23 and also by the roll 24 onthe same shaft with which is fixed a sprocket wheel 26. The sprocket wheel 26 isdriven from shaft 43 by a sprocket chain 44 which passes around the sprocket wheel on 'the far end of theshaft 43, thence partly around sprocket wheel 26 and thence around an idle sprocket wheel 28. Shaft 43- is drivenby'a" Sprocket chain'27 which passes around sprocket wheel 25 and around I sprocket wheel29 on shaft 30 which is driven by} anysuitable. means.

1, On the shaft 16, whose movement actu- I atesthe pan 5, is fixed a sprocket wheel. 31

which isdriven by a sprocket chain 32 which passes around sprocket wheel 31, also art way around a sprocket wheel 33 fixed on thef s haft" 30 and thence overtwo sprocket pulleys back to sprocket wheel 31.

,On the rock shaft 34 is fixed an ordinary paper delivery fly having a stop bar 35 near it's'lower end. Mounted on the rock shaft 7 34" is a pulley 36 :towhich is fixed one end of; the strap 3'Z,the other end of the strap being: connected with a spring 38 attached to th e main frame, Shaft 34 also "carries a frlction pulley 41 arranged to cooperate the friction wheel 18, for which purposefthe friction strip 19 on wheel 18 is pro- When friction; wheel :18 rotates, its fr ct on surface Idrives pulley 41during the time, that the friction ,strip is in contact .lits pulley, thereby rocking the shaft and' causing the delivery-fly 42 to move backward from ts receiving position shown fifiEigfl; tojdeposit on a table the paper tubes; that have been d eliverecl to it bythe apes 2,1" and 22. 7 When the friction strip 19 has passed out ofcontact with the pul- I ley 41,-'the strap 37 rocks the shaft 34 back- V a ward to return the delivery'fiy to its res ceiving" position.

reciprocating pan When the front or seamed edge of the I paper tube has been delivered between the tapes 21 and 22 upon the forward movement of the pan 5, the tube is carried by these tapes over the roll 23 from which it is deposited upon the delivery fly 42, the stop bar 35 preventing the tube from sliding off the fly. a

While the inventionis shown in whatis believed to be its best form, it is to be understood that various changes in the structure and arrangement of the partsmay be made without departing from the scope of the invention,
